[Moabusers] Major problem with SR

[Brock Palen]

We have a sr defined like so:

SRCFG[csem]     NODEFEATURES=csem
SRCFG[csem]     CLASSLIST=csem
SRCFG[csem]     TASKCOUNT=28
SRCFG[csem]     PERIOD=DAY
SRCFG[csem]     DEPTH=10
SRCFG[csem]     ACCESS=DEDICATED
SRCFG[csem]     FLAGS=IGNSTATE

Problem though is jobs owned by a class other than csem is being  
placed on the nodes,  causing those node to not be available.  We are  
pared with torque-2.1.1  a check job on one of the jobs that should  
not be on the nodes is below

job 1617

AName: R2_12x36

StartPriority:  10451
Reservation '1617' (-2:56:00 -> 7:59:00  Duration: 10:55:00)


Checknode also shows the node as the current active csem reservation  
was active on it before the job started on it!
Output

checknode nyx337

snip....
csem.1029x1  User  -14:10:55 -> 9:49:05 (1:00:00:00)
     Blocked Resources at -00:00:44   Procs: 4/4 (100.00%)  Mem: 0/3901

snip...
1617x1  Job:Running  -2:56:30 -> 7:58:30 (10:55:00)

This job should not be on this node what could be causing this problem?
